This article studies the question of flexure shape of yarn in fabric.Using the CU-2 textile fiber degree of fineness instrumental measures the geometric parameter of flexure shape of yarn in fabric

using MATLAB for fabric slice chart processing.And then the microscopic image analysis software of the CU-2 textile fiber degree of fineness instrumental is used to obtain the geometric parameters of yarn buckling shape

the use of the geometric parameters can be measured to calculate the fabric structure phase

describe the form of yarn buckling

it is a basis work to simulate yarn buckling shape really.
